This looks a runtime bug. Here's a partial stack trace:
Stacktrace:

  at (wrapper managed-to-native) System.ValueType.InternalGetHashCode
(object,object[]&) <0x00003>
  at (wrapper managed-to-native) System.ValueType.InternalGetHashCode

  at System.Collections.Hashtable.GetHash (object) <0x00038>
  at System.Collections.Hashtable.Find (object) <0x00044>

And inside gdb:
0x0812b57f in mono_string_hash (s=0x3bfb0) at domain.c:1081
1081            h = (h << 5) - h + *p;
(gdb) bt
